Speaking of the Lazarus ship, has anyone figured out what it was? I mean, Star Trek recycled everything, and while I know the dome from the ship appeared as set dressing for other episodes, the ship only being used once makes me think it was something rented or borrowed, since otherwise I'd have expected to see it reused.

It almost looks like part of an amusement park ride. But, I still love it. You could picture George Jetson driving it to work.
